Optically controlled thermophoretic trapping of single nano-objects.

ACS nano

Braun M, Cichos F.
PMID: 24215133
ACS Nano. 2013 Dec 23;7(12):11200-8. doi: 10.1021/nn404980k. Epub 2013 Nov 13.

Brownian motion is driven by thermal fluctuations and becoming more efficient for decreasing size and elevated temperatures. Here, we show that despite the increased fluctuations local temperature fields can be used to localize and control single nano-objects in solution....

United European Gastroenterol J. 2016 Apr;4(2):172-6. doi: 10.1177/2050640616629079. Epub 2016 Feb 03.

To develop standards for high quality of gastrointestinal endoscopy, the European Society of Gastrointestinal Endoscopy (ESGE) has established the ESGE Quality Improvement Committee. A prerequisite for quality assurance and improvement for all gastrointestinal endoscopy procedures is state-of-the-art integrated digital...

Contacts for organic switches with carbon-nanotube leads.

Nanotechnology

Wierzbowska M, Rode MF, Sadek M, Sobolewski AL.
PMID: 26011251
Nanotechnology. 2015 Jun 19;26(24):245201. doi: 10.1088/0957-4484/26/24/245201. Epub 2015 May 26.

We focus on two classes of organic switches operating due to the photo- or field-induced proton transfer (PT) process. By means of first-principles simulations, we search for the atomic contacts that strengthen diversity of the two swapped current-voltage (I-V)...

Comment on "Optimal detection angle in sub-diffraction resolution photothermal microscopy: application for high sensitivity imaging of biological tissues".

Optics express

Selmke M, Cichos F.
PMID: 25836891
Opt Express. 2015 Mar 09;23(5):6747-50. doi: 10.1364/OE.23.006747.

A recent publication [Opt. Express, 22(16), 18833-18842 (2014)] discusses the optimal detection aperture in photothermal single particle microscopy. This new theory is in contradiction with rigorous ab-initio electrodynamic calculations. Nonetheless, the experimentally verified conclusion that a maximum signal occurs...

I drink for my liver, Doc: emerging evidence that coffee prevents cirrhosis.

F1000Research

Feld JJ, Lavoie ÉG, Michel F, Dranoff JA.
PMID: 25977756
F1000Res. 2015 Apr 21;4:95. doi: 10.12688/f1000research.6368.1. eCollection 2015.

Evidence demonstrating that regular ingestion of coffee has salutary effects on patients with chronic liver disease is accumulating rapidly. Specifically, it appears that coffee ingestion can slow the progression of liver fibrosis, preventing cirrhosis and hepatocellular carcinoma (HCC). This...

Trapping of single nano-objects in dynamic temperature fields.

Physical chemistry chemical physics : PCCP

Braun M, Würger A, Cichos F.
PMID: 24939651
Phys Chem Chem Phys. 2014 Aug 07;16(29):15207-13. doi: 10.1039/c4cp01560f. Epub 2014 Jun 17.

In this article we explore the dynamics of a Brownian particle in a feedback-free dynamic thermophoretic trap. The trap contains a focused laser beam heating a circular gold structure locally and creating a repulsive thermal potential for a Brownian...

Metal nanoparticle based all-optical photothermal light modulator.

PMID: 24437364
ACS Nano. 2014 Feb 25;8(2):1893-8. doi: 10.1021/nn406389f. Epub 2014 Jan 23.

We present a simple scheme for the manipulation of light intensity by light mediated by a dissipative process. The implementation employs the heat released by an optically excited plasmonic metal nanoparticle to control the size of an isotropic bubble...
